Hi,
There is lot of information available about how a Fabric extender connects to the Fabric interconnect. e.g. SFP+ ports, cabling etc.
I am bit a confused, how does connectivity happen between the blade server and fabric extender inside the chassis.
The information available only gives us idea about the possible network cards in the blade servers.
I want to understand, how actual connectivity is done between the blade servers and fabric extenders.
Is it through some cables or anything else? Please help.
Thanks,
Sushant

Hi Walter,
Thanks for responding!!
My question is mostly on the physical connectivity between Fabric Extender and Blade server.
In my case I am considering the following:
1 B200M3 (1 UCSB-MLOM-40G-01) blade server
1 2204 XP Fabric Extender
I checked the links but couldn’t find my answer.
May be I need a little explanation.
Please explain about the physically connectivity in little detail.
Thanks,
Sushant

Hi Walter,
I have looked into that document before :)
My questions is on the physical connectivity.
How are they connected physically, I mean LAN cable, twin copper cable etc.?
What is the physically connectivity between them?
Thanks & Regards,

Blade Server - IOM (FEX) goes over the chassis backplane.
the 2204 has 2x10G backplane connections per chassis slot (and fabric)
the 2208 has 4x10G backplane connections per chassis slot (and fabric)
All I/O adaptors (VIC-1240/1280) are dual homed.
No external cables !
